Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and more specifically, to a fully hydraulic bulldozer. Background Technology

[0002] Fully hydraulic bulldozers, with their efficient power transmission and flexible maneuverability, are widely used in complex operation scenarios such as earthmoving and mining. As the core power component of a fully hydraulic bulldozer, the rationality of its installation structure design directly affects the equipment's operational stability and ease of maintenance. Currently, existing fully hydraulic bulldozers typically integrate the drive motor, reducer, and bulldozer frame. When the drive motor malfunctions and requires repair or replacement, maintenance personnel must disassemble the reducer, motor, and frame as a whole to inspect the motor and related components. This process not only involves the disassembly and assembly of numerous parts, consuming significant manpower and time, but also risks damaging other components during frame disassembly, increasing maintenance risks and costs. Furthermore, the complex disassembly process significantly prolongs equipment downtime, reduces project efficiency, and results in substantial economic losses for the construction company.

[0003] These problems urgently need to be solved, therefore, this utility model provides a fully hydraulic bulldozer. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fully hydraulic bulldozer that can simplify the maintenance process of the drive motor, improve maintenance efficiency and reduce maintenance costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is: to provide a fully hydraulic bulldozer including a frame, a mounting structure, a travel motor and a reducer, wherein the mounting structure includes a reducer mounting seat welded to the frame and a flange, and the travel motor and the reducer are mounted on the reducer mounting seat through the flange.

[0006] In this embodiment, specifically, the flange has mounting holes 2 evenly distributed around its outer circumference, and mounting holes 3 evenly distributed around its inner axial circumference.

[0007] In this embodiment, the mounting structure specifically includes washers and bolts.

[0008] In this embodiment, specifically, mounting holes 1 are uniformly provided circumferentially on the outer surface of the reducer mounting base, and the bolt passes through the mounting holes 1 and 2 to fix the flange 1 on the reducer mounting base.

[0009] In this embodiment, specifically, a flange two is welded to the outer ring of the reducer facing the vehicle frame, and a mounting hole four is provided on the flange two.

[0010] In this embodiment, specifically, the bolt passes through the fourth mounting hole and the third mounting hole to mount the reducer onto the first flange.

[0011] In this embodiment, specifically, a flange three is welded to the outer ring of the reducer on the side away from the vehicle frame, and a mounting hole five is provided on the flange two.

[0012] In this embodiment, specifically, the mounting structures are symmetrically provided on both sides of the vehicle frame.

[0013] In this embodiment, specifically, the walking motor is disposed inside the reducer mounting base, and the reducer is disposed outside the reducer mounting base.

[0014] In this embodiment, specifically, the nut of the bolt fixed in the second mounting hole is positioned facing outwards from the frame, and the nut of the bolt fixed in the third mounting hole is positioned facing inwards from the frame.

[0015] The beneficial effects of this utility model are as follows: This utility model discloses a fully hydraulic bulldozer, which includes a frame, a mounting structure, a travel motor, and a reducer. The mounting structure includes a reducer mounting seat welded to the frame and a flange. The travel motor and the reducer are mounted on the reducer mounting seat via the flange. The flange has two rings of mounting holes. The flange has a second ring of mounting holes evenly distributed around its outer circumference and a third ring of mounting holes evenly distributed around its inner axial circumference. Through the double-ring fixing hole design of the flange, the outer ring connects to the main frame and the inner ring connects to the reducer, realizing the modular integrated installation of the travel motor and the reducer.

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figure 1-3 As shown, this utility model discloses a fully hydraulic bulldozer, including a frame 1, a mounting structure 2, a travel motor 3 and a reducer 4. The mounting structure 2 serves as the core connecting component, enabling precise assembly and efficient maintenance of the travel motor 3 and the reducer 4 on the frame 1.

[0021] In this embodiment, specifically, the mounting structure 2 includes a reducer mounting base 21 welded and fixed to the frame 1, a flange 22 for intermediate connection, and washers 23 and bolts 24 for auxiliary fixing. The travel motor 3 and the reducer 4 are connected in layers through the flange 22 to form a modular assembly and fixed to the reducer mounting base 21. The overall structure combines connection rigidity and maintenance flexibility.

[0022] In this embodiment, specifically, flange 22 adopts an independent hole layout for its inner and outer rings. Mounting holes 221 are evenly distributed around the outer ring of flange 22 for connection to the reducer mounting base 21; corresponding mounting holes 222 are provided around the inner ring of flange 22 for connection to the reducer 4. This dual-ring separate hole design ensures that the outer ring bolts are responsible for fixing the assembly to the frame, while the inner ring bolts are responsible for connecting the reducer to the flange. The two functions are independent and do not interfere with each other.

[0023] In this embodiment, specifically, the reducer mounting base 21 serves as a basic load-bearing component, with mounting holes 211 evenly spaced on its outer surface. Bolts 24 pass through the mounting holes 211 and the mounting holes 221 of the flange 22, and together with washers 23, the flange 22 is rigidly fixed to the frame 1.

[0024] In this embodiment, specifically, a flange 41 is welded to the outer ring of the reducer 4 facing the frame 1. The mounting holes 411 on the flange 41 are precisely aligned with the mounting holes 222 on the flange 22. The reducer 4 is fastened to the flange 22 by the cooperation of bolts 24 and washers 23.

[0025] In this embodiment, specifically, the mounting structure 2 is symmetrically arranged on both sides of the frame 1, the walking motor 3 is built into the cavity of the reducer mounting base 21, and the reducer 4 is externally mounted on the outside of the reducer mounting base 21. The nuts of the bolts 24 are arranged in opposite directions, with the bolts and nuts fixed in the second mounting hole 221 facing the outside of the frame 1, and the bolts and nuts fixed in the third mounting hole 222 facing the inside of the frame 1. This avoids interference from tool operations during disassembly and assembly, and also uses the difference in nut orientation to visually distinguish the function of the bolts.

[0026] The installation process of this utility model of a fully hydraulic bulldozer is as follows: The travel motor 3 is pre-installed inside the reducer 4. The travel motor 3 and the reducer 4 are fixed on the flange 22 by passing the bolts 24 through the mounting holes 411 of the second flange 41 and 222 of the first flange 22. The assembly is then fixed on the reducer mounting base 21 of the frame 1 by passing the bolts 24 through the mounting holes 211 of the reducer mounting base 21 and 221 of the flange 22. After the pipeline connection is completed, the overall installation is achieved.

[0027] The beneficial effects of this utility model of a fully hydraulic bulldozer are as follows: 1. The double-ring hole design of flange 22 enables modular integration and fixing of the travel motor 3 and the reducer 4. During maintenance, there is no need to disassemble the trolley frame. Only the bolts (outer ring holes) connecting flange 22 and reducer mounting base 21 and related pipelines need to be removed to remove the reducer 4 and travel motor 3 as a whole, which greatly shortens maintenance time and reduces equipment downtime costs.

[0028] 2. The compact layout and flange integration design of the "internal travel motor 3-external reducer 4" significantly reduces the installation space of the drive system, leaving more space for the arrangement of other components of the bulldozer 100.
